Hine's emerald dragonfly (Somatochlora hineana)
This dragonfly was originally discovered in Ohio, but by the mid-1900's it was believed to be extinct.
In 1988 a specimen collected in the Des Plaines River Valley (southwest of Chicago) in Illinois was later identified as this species. Subsequent surveys uncovered additional populations there, as well as northeast Wisconsin, Michigan, and Missouri. All are associated with areas of groundwater-fed wetlands that are perched over limestone bedrock.
The Hine's emerald dragonfly, listed as endangered, is found in Illinois, Missouri, Michigan and Wisconsin. Adults lay their eggs in small streams in fens and sedge meadows. After hatching, the aquatic larvae spend up to five years in wetlands before completely maturing and emerging as adult dragonflies.
